In underground fuel systems, Dualoy 3000/L r fiberglass pipe and fittings give you something no other product has (including steel). Dualoy 3000/L from Ameron is the best UL-listed piping available for underground fuel system construction and rehabilitation. _ - --- - Manufactured from chemically inert ' �-- materials, Dualoy 3000/L fiberglass ? '` , pipe and fittings resist external corrosion far better than cathodically protected steel. The Dualoy 3000/L liner delivers features and performance no other UL-listed piping system has. Resilient and holiday-free, the flexible inner liner is an added layer of protection inside the structural pipe wall. Competitive fiberglass r pipe has no liner. Galvanized steel pipe can descale 4 when exposed to modern no-lead fuels.
